Getting compared to abusive ex?

Me and my girlfriend were having an argument over a miss communication about a text sent earlier in the day where she thought I was making fun of her but I was making fun of the situation. I had apologized about it and told her I didn't mean it in that way and wouldn't try to do that and not do that in the future.

The argument continued and I said how about we pause and I can leave for a bit so we can calm down. She took this as me asking her "do you want me to leave." Apparently this was a term her abusive ex would say all the time. She immediately said I was the same as him. I don't know what to say to this and was extremely hurt by this comment. Looking for support
